Climatic‐niche breadth, niche position, and speciation in lizards and snakes
Moreira, Matthew Owen; Wiens, John J.; Fonseca, Carlos; Rojas, DannyAim: The climatic niche is associated with diversification in many groups of animals and plants. However, the relationships between climatic-niche breadth evolution, climatic-niche position evolution, and speciation remain underexplored. It is particularly unclear whether changes in climatic-niche breadth are related to diversification. We tested two hypotheses relating niche breadth, niche position, and specia...
Potential persistence of high‐mountain lizards
Moreira, Matthew Owen; Fonseca, Carlos; Rojas, DannyClimate change will impact environments globally. These changes, however, can affect species or regions differently. The upward limitation of highmountain species suggests these are especially prone to the effects of climate change. We assess the impact of future climate scenarios on high-mountain species' suitable climatic niches. We gathered 1351 occurrence records of highmountain (>2000 m asl) squamates and ...
ES-sim-GLM, a Multiple Regression Trait-Dependent Diversification Approach
Moreira, Matthew O.; Fonseca, Carlos; Rojas, DannyIdentifying the role of quantitative variables on speciation rates is among the main purposes of trait-dependent diversification methods. ES-sim, a recent simulation-based approach that relies on Pearson’s correlations, allows testing trait-dependent diversification for single regression models. Here, we modified this approach to include generalized linear models and two independent variables. To examine the ef...
Parthenogenesis is self-destructive for scaled reptiles
Moreira, Matthew Owen; Fonseca, Carlos; Rojas, DannyParthenogenesis is rare in nature. With 39 described true parthenogens, scaled reptiles (Squamata) are the only vertebrates that evolved this reproductive strategy. Parthenogenesis is ecologically advantageous in the short term, but the young age and rarity of parthenogenetic species indicate it is less advantageous in the long term. This suggests parthenogenesis is self-destructive: it arises often but is lost...
Updated distribution maps for neotropical bats in the superfamily Noctilionoidea
Rojas, Danny; Moreira, Matthew; Pereira, Maria João Ramos; Fonseca, Carlos; Dávalos, Liliana M.The IUCN provides a spatial database for many species, including terrestrial mammals. This database includes shapefiles with taxonomic information and the extent of occurrence for each species, and has been used in hundreds of studies in ecology, biogeography and conservation. Here we provide updated distribution maps that comprise the extent of occurrence of the neotropical bat species in the superfamily Nocti...
